' I SPACING DEVICE.

Specification of Letters Patent.

Patented May 4, 1920.

Application filed August 6, 1918. Serial No. 248,660.

To all "whom it may concern:

Be it known that we, Gnonon H. T01) and EDWARD H. BECK, both subjects of the King of Great Britain, and residents of the city of Toronto, county of YorlqProvince of Ontario, in theDominion of Canada, have invented certain new and useful Improvements in Spacing Devices, described in the following specification and illustrated in the accompanying drawings, thatv form part of the same.

The principal objects of this invention are to facilitate the dividing of long articles, such as bars of metal, into a number of equal lengths and to provide a device which may be easily and quickly manipulated to divide any inequality in the length of the bars uni formly among the several divisions or pieces into which the member is to be cut or marked.

A still further object is to provide a device which will be very simple inconstructi'on,

positive in operation and easily manipulated.

The principal feature of the invention consists in connecting a plurality of markers with levers of the lazy tong-form, the markers being moved upon a suitable guide.

In the drawings Figure 1 is a plan View of a marker constructed according to this invention.

Fig. 2 is an elevational View.

Fig. 8 is an underside plan view' Fig. 4 is an enlarged cross sectional view through one of the pivotal connections of the operating levers and Fig. 5 is an enlarged longitudinal sectional detail through one of the markers and the pivotal connection.

The device shown in the accompanying drawings is particularly adapted for use in the marking of metal bars prior to being out into billets, but there may be many forms of adaptation of the invention for other purposes.

The construction shown consists of a channel bar 1 having the flanges 2 turned downwardly and upon the top side of this channel is secured a pair of guides 3 which are parallelly spaced and suitably secured throughout their lengths. Between these guides is arranged a plurality of angle bar brackets 4 having their horizontal flanges slidably resting upon the face of the channel 1 and the ends engaging the guides 3 with the other flange extending upward.

Longitliidinal slots 5 are cut in the channel 1 and each of the angle brackets 4: has cen trally secured thereto a bolt 6 which eX- tends through the slot immediately thereunder and upon each of these bolts is pivoted a pair of lever'members 7.

' The adjacent ends of eachpair of levers are connected to the adjacent ends of the adjacent pair of levers throughout the length of the device and as said levers are all of a uniform length, the brackets will consequently be spaced equidistant and no matter how the device may be moved to lengthen or shorten thelazy tong structure formed by the levers 7, the pivot bolts of the levers will always be arranged at equal dis tances apart, consequently the upright flanges of the brackets 4 willbe equidistant and these brackets form the guides for any suitable form of marking device which it is desired to be used.

One end of the lazy tong arrangement of leversis secured to the channel support by means of the pivotal links 8 so as to allow of the proper movement of the levers, the opposite end is of course free.

In order to operate the device it is necessary to apply the moving force at several points in the length thereof, as the weight of the moving members of the construction would be too heavy to be overcome by operating from either end.

In order to accomplish the easy movement of the collapsible member, a bracket 9 is arranged intermediate of the length of the channel and is secured to one side thereof. Upon this bracket is pivotally mounted a lever 10 and to the center of this lever is pivotally connected an operating rod 11, the opposite end of which is secured to the operating lever 12 pivotally supported at the end of the channel 1. A pair of rods 13 and 14 is pivotally secured to the lever 10 between its pivot point and the point of connection of the rod 11 and the opposite ends of these rods are connected to the pivot bolts 6 at two different points in the length of the structure.

A similar pair of rods 15 and 16 is pivotally connected to the outer end of the lever 10 and to the bolts 6, the outer rod 16 being connected to the extreme free end of the lazy tong device.

With this arrangement of mechanism by the simple operation of the lever 12, the lever 10 is swung on its pivot and through the rods 13, 14, 15 and 16, the lazy tong lever mechanism is operated to be contracted or extended and as it is thus operated, the brackets A which form the guides for the marking device, Whatever it may be, are

moved in exact proportion so that the spaces between any two brackets will be equal to the space between any two other brackets and any member such as a pipe or rod or post, which it may be desirable to mark can very quickly be marked in equal divisions.

A bracket 17 is arranged at the end oi the channel 1. opposite to that at which the lever 12 is secured and in this bracket is arranged an adjusting screw 18 against which the member to be marked is butted.

This device may be modified considerably to be adapted for various uses but in the present form the vertical face of the angle brackets 4 forms a guide for the acetylene torch which is used in the nicking of bars for the purpose of breaking them into uniform lengths for making billets for the forming of shells.

It effects a very great saving in time in being able to divide bars which are not of the same length into a uniform. number of pieces and by means of the mechanism described this result has been accomplished.

What we claim as our invention is 1. A spacing device comprising, a bar having a guide way formed on the top thereof and having longitudinal slots arranged centrally thereof, a plurality of guide brackets slidably arranged in said guide way, bolts secured to said brackets and extending through the slots, a lazy tong structure connected to said bolts, beneath said guide, and means for expanding and contracting said lazy tong structure to move said guidebrackets in a uniform spacing.

2. A spacing device comprising, a plurality of marking guides, a slide supporting said guides, a lazy tong structure connected 1 with said guides secured on one end of the slide, a lever pivotally supported. interme diate of the length of said lazy tong structure, link rods pivotally connected to said lever and connected to said lazy tong strucnected' to said lever intermediate of its length, an operating lever secured at one end 01": the device and connected to said rod, a pair of rods pivotally secured to said lever between the point of connection of the operating rod and its pivot and having their ends pivotally connected to the pivot bolts 01": said lazy tong structure at different points in the portion adjacent to the secured end, and a pair of rods pivotally se cured to the outer end of said lever and I having their outer ends connected to the bolts of said lazy tong structure between the transverse lever and the free end.
